vterm-toggle Toggle vterm buffer

emacs-libvterm is fully-fledged terminal emulator inside GNU Emacs based on libvterm.

This package provides the command vterm-toggle which toggles between the vterm buffer and whatever buffer you are editing.

This is done in an "intelligent" way. Features are:

Starts a vterm if none is existent.
Minimum distortion of your window configuration.
When done in the vterm-buffer you are returned to the same window configuration you had before you toggled to the shell.
If you desire, you automagically get a cd command in the shell to the directory where your current buffers file exists, just call vterm-toggle-cd instead of vterm-toggle.

(global-set-key [f2] 'vterm-toggle)
(global-set-key [C-f2] 'vterm-toggle-cd)

;; you can cd to the directory where your previous buffer file exists
;; after you have toggle to the vterm buffer with `vterm-toggle'.
(define-key vterm-mode-map [(control return)]   #'vterm-toggle-insert-cd)

;Switch to next vterm buffer
(define-key vterm-mode-map (kbd "s-n")   'vterm-toggle-forward)
;Switch to previous vterm buffer
(define-key vterm-mode-map (kbd "s-p")   'vterm-toggle-backward)

Customize

vterm-toggle-cd-auto-create-buffer

With

(setq vterm-toggle-cd-auto-create-buffer nil)

vterm-toggle-cd would activate a recent vterm buffer even if no prompt can be found (with vterm-toggle-use-dedicated-buffer still nil). So when the current buffer is not a vterm buffer, it would always activate a recent vterm buffer if there is one but would only insert cd if the prompt is available. And you can bind

(define-key vterm-mode-map [(control return)]   #'vterm-toggle-insert-cd)

vterm-toggle-reset-window-configration-after-exit

t Reset window configuration after vterm buffer is killed. 'kill-window-only Kill Window only.

vterm-toggle-hide-method

delete-window Delete vterm window
nil Toggle without closing the vterm window, just jump back-and-forth between vterm and a code buffer.
reset-window-configration Reset window configration

show vterm buffer in current window

(setq vterm-toggle-fullscreen-p nil)
(add-to-list 'display-buffer-alist
             '((lambda (buffer-or-name _)
                   (let ((buffer (get-buffer buffer-or-name)))
                     (with-current-buffer buffer
                       (or (equal major-mode 'vterm-mode)
                           (string-prefix-p vterm-buffer-name (buffer-name buffer))))))
         (display-buffer-reuse-window display-buffer-same-window)))

show vterm buffer in bottom side

(setq vterm-toggle-fullscreen-p nil)
(add-to-list 'display-buffer-alist
             '((lambda (buffer-or-name _)
                   (let ((buffer (get-buffer buffer-or-name)))
                     (with-current-buffer buffer
                       (or (equal major-mode 'vterm-mode)
                           (string-prefix-p vterm-buffer-name (buffer-name buffer))))))
                (display-buffer-reuse-window display-buffer-at-bottom)
                ;;(display-buffer-reuse-window display-buffer-in-direction)
                ;;display-buffer-in-direction/direction/dedicated is added in emacs27
                ;;(direction . bottom)
                ;;(dedicated . t) ;dedicated is supported in emacs27
                (reusable-frames . visible)
                (window-height . 0.3)))

show vterm buffer in side window

If you want show vterm buffer at bottom side window:

(setq vterm-toggle-fullscreen-p nil)
(add-to-list 'display-buffer-alist
             '((lambda (buffer-or-name _)
                   (let ((buffer (get-buffer buffer-or-name)))
                     (with-current-buffer buffer
                       (or (equal major-mode 'vterm-mode)
                           (string-prefix-p vterm-buffer-name (buffer-name buffer))))))
               (display-buffer-reuse-window display-buffer-in-side-window)
               (side . bottom)
               ;;(dedicated . t) ;dedicated is supported in emacs27
               (reusable-frames . visible)
               (window-height . 0.3)))

work with centaur-tabs (select next/prev vterm buffer)

https://github.com/ema2159/centaur-tabs/

You can customize centaur-tabs and make all vterm buffer in a tab group, and use centaur-tabs-forward and centaur-tabs-backward switch from one vterm buffer to another.

(global-set-key  (kbd "s-n") 'centaur-tabs-forward)
(global-set-key  (kbd "s-p") 'centaur-tabs-backward)

(setq centaur-tabs-buffer-groups-function 'vmacs-awesome-tab-buffer-groups)
(defun vmacs-awesome-tab-buffer-groups ()
  "`vmacs-awesome-tab-buffer-groups' control buffers' group rules. "
  (list
   (cond
    ((derived-mode-p 'eshell-mode 'term-mode 'shell-mode 'vterm-mode)
     "Term")
    ((string-match-p (rx (or
                          "\*Helm"
                          "\*helm"
                          "\*tramp"
                          "\*Completions\*"
                          "\*sdcv\*"
                          "\*Messages\*"
                          "\*Ido Completions\*"
                          ))
                     (buffer-name))
     "Emacs")
    (t "Common"))))

(setq vterm-toggle--vterm-buffer-p-function 'vmacs-term-mode-p)
(defun vmacs-term-mode-p(&optional args)
  (derived-mode-p 'eshell-mode 'term-mode 'shell-mode 'vterm-mode))

vterm-toggle-use-dedicated-buffer

When vterm-toggle-use-dedicated-buffer is not nil, you can toggle to a dedicated vterm buffer.

you can toggle to different dedicated buffer for different purpose. For example, I want to replace default compile with my vterm-compile

(defvar vterm-compile-dedicated-buffer nil)
(defun vterm-compile ()
  (interactive)
  (let ((vterm-toggle-use-dedicated-buffer t)
        (vterm-toggle--vterm-dedicated-buffer vterm-compile-dedicated-buffer))
    (with-current-buffer (vterm-toggle-cd)
      (setq vterm-compile-dedicated-buffer (current-buffer))
      (rename-buffer "term compile")
      (compilation-shell-minor-mode 1)
      (vterm-send-string compile-command t)
      (vterm-send-return))
    )
  )
